------------------------------------------------------------------
These engines are a bit different than the LS.

-Engine mount pattern is different

-Header flange pattern & tube spacing is different.
These are what come on the LT1 crate:

And these are a potentially more swap-friendly truck manifold:


-The new C7 has electric steering so no hydraulic power steering pump is available yet. Street & Performance has a serpentine drive with an aftermarket Sanden AC compressor, about $1900 for the kit.
The GM serpentine kit with AC and alternator only is part number 19329990.

-LT1/4's have an 8-bolt crankshaft pattern, which is the same pattern as the LSA. The clutch/flywheel kits for the LSA fit the LT1/4.

-The bell housing pattern is just about identical.. But the top bolt is in a different location. The new 4L65/70 E's that come in the connect & cruise kits for these engines have an extra hole to bolt to them. See picture below. At this time we're unsure how different the 4L80E will fit.


-The GM steel bell housing for T56's has the hole in the right spot, and is large to accept their clutch kit.
-There are TWO different oil pans - dry sump & wet sump. The dry sump has a shorter (front to back) sump. Wet sump oil pans may require notching. Don't worry, there's plenty of room in the front of the sump to make that happen.
Wet sump:



Note these oil pans have no gasket.. Just RTV! And they're pretty heavy....

-The T56 Super Magnum that GM released is the same as the Magnum dimensionally, but the shifter is different, and there is a 40-tooth reluctor for the speed sensor, which is only required for the E-Rod systems. It's also a close-ratio setup.

We'll update this thread with more details as they come available! If anyone has any more knowledge on these, feel free to post a reply- we all have room to learn about these Gen 5's
